In my experience when I did fall asleep wearing my hearing aids was only in the off chance that I'd hear the alarm clock in the morning so my kids don't go late to school. (I've had like a million vibrating alarm clocks and even ones with light and either they break or I'm a heavy sleeper...) Anyway, I found that for me it wasn't good because my ear would hurt, often times get swollen and there would be pressure... I'd get a sore on the upper part of earlobe where the tubing connects to aid. I also found that sometimes it fell off (or I took it off when I slept?) and it'd be a pain to find in the morning. I remember I woke up panicking that I broke it or that I lost it. If you have no physical issues wearing them to bed, then by all means do whatever floats your boat. But the battery will not last as long (and batteries ain't cheap), the tubes will need to be replaced more often than normal.
